Network Application
This section provides you a few samples of network topology in which the switch
is used. In general, the MIL-SEM24T4GPA Switch is designed to be used as a
desktop or segment switch.
Desktop Application
The MIL-SEM24T4GPA Switch is designed to be a desktop size switch that is an
ideal solution for small workgroup. The Switch can be used as a stand-alone
switch to which personal computers, server, printer server are directly connected
to form small workgroup.
Segment Application
For enterprise networks where large data broadcast are constantly processed,
this switch is suitable for department user to connect to the corporate backbone.
User can connect PCs, workstations, and servers to each other via the
MIL-SEM24T4GPA Switch. All the devices in this network can communicate with
each other. Connecting servers to the backbone switch allow other users to
access the data of server.
The switch automatically learns node address, which are subsequently used to
filter and forward all traffic based on the destination address. User can use any of
the RJ-45 port of the MIL-SEM24T4GPA Switch to connect with another Switch or
Hub to interconnect each of user’s small-switched workgroups to form a larger
switched network.

Web-Based Management
This section introduces the configuration and functions of the Web-Based
management.
About Web-based Management
On CPU board of the switch, there is an embedded HTML web site residing in
flash memory, which offers advanced management features and allow users to
manage the switch from anywhere on the network through a standard browser
such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 5.0 or later version. And,
it is applied for Java Applets for reducing network bandwidth consumption,
enhance access speed and present an easy viewing screen.
[NOTE] By default, IE5.0 or later version does not allow Java Applets to activate
sockets. The user has to explicitly modify the browser setting to enable Java
Applets to operate network ports.
Preparing for Web Management
Before using web management, install the switch on the network and make sure
that any one of the PCs on the network can connect with the switch through the
web browser. The switches default value of IP, subnet mask and password are as
below:

Page 26
switched inter-network. Actually, the link does not have an inherent total bandwidth
equal to the sum of its component physical links. Traffic in a trunk is distributed
across an individual link within the trunk in a deterministic method that called a hash
algorithm. Traffic pattern on the network should be considered carefully before you
apply it. When a proper hash algorithm is used, traffic is kind of randomly decided to
be transmitted across either link within the trunk and load balancing will be seen.

VLAN Setting
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which would allow user to isolate network traffic, and therefore only the
members of VLAN will receive traffic from the members of the same VLAN.
Basically, creating a VLAN from a switch is logically equivalent to reconnecting a
group of network devices to another Layer 2 switch. However, all the network

LACP Setting
The Link Aggregation Control Protocol (LACP) provides a standardized means for
exchanging information between Partner Systems on a link to allow their Link
Aggregation Control instances to reach agreement on the identity of the Link
Aggregation Group to which the link belongs, move the link to that Link
Aggregation Group, and enable its transmission and reception functions in an
orderly manner. Link aggregation lets user group up to eight consecutive ports
into a single dedicated connection. This feature can expand bandwidth to a device
on the network. LACP operation requires full-duplex mode, more detail
information refers to IEEE 802.3ad.

dependent upon whether the port concerned can only be connected to one
other bridge exactly (i.e. it is served by a point-to-point LAN segment), or can
be connected to two or more bridges (i.e. it is served by a shared medium
LAN segment). This function allows the P2P status of the link to be

SNMP Setting
Simple Network Management Protocol (SNMP) is the protocol developed to
manage nodes (servers, workstations, routers, switches and hubs etc.) on an IP
network. SNMP enables network administrators to manage network performance,
find and solve network problems, and plan for network growth. Network
management systems learn of problems by receiving traps or change notices
from network devices implementing SNMP.

Troubleshooting
This section is intended to help user solve the most common problems on the
MIL-SEM24T4GPA Switch.
Incorrect connections
The switch port can automatically detect straight or crossover cable when user
link switch with other Ethernet device. As for the RJ-45 connector, it should use
correct UTP or STP cable; 10/100Mbps port use 2-pairs twisted cable while
Gigabit 1000T port use 4 pairs twisted cable. If the RJ-45 connector is not correct
pinned on right position, then the link will fail. As for fiber connector, please notice
the fiber cable mode and fiber module should match.
Faulty or loose cables
Look for loose or obviously faulty connections. If they appear to be OK, make sure
the connections are snug. If that does not correct the problem, try a different
cable.
Non-standard cables
Non-standard and miss-wired cables may cause numerous network collisions and
other network problem, and can seriously impair network performance. A
category 5-cable tester is a recommended tool for every 100Base-T network
installation.
RJ-45 ports:
use unshielded twisted-pair (UTP) or shield twisted-pair ( STP )
cable for RJ-45 connections: 100 Category 3, 4 or 5 cable for 10Mbps
connections or 100 Category 5 cable for 100Mbps connections. Also be sure
that the length of any twisted-pair connection does not exceed 100 meters (328
56
Page 57
feet). Gigabit port should use Cat-5 or cat-5e cable for 1000Mbps connections.
The length does not exceed 100 meters.
Improper Network Topologies
It is important to make sure that you have a valid network topology. Common
topology faults include excessive cable length and too many repeaters (hubs)
between end nodes. In addition, you should make sure that your network topology
contains no data path loops. Between any two end nodes, there should be only
one active cabling path at any time. Data path loops will cause broadcast storms
that will severely impact your network performance.
Diagnosing LED Indicators
The Switch can be easily monitored through panel indicators, which describes
common problems you may encounter and where you can find possible solutions,
to assist in identifying problems.
If the power indicator does not light on when the power cord is plugged in, you
may have a problem with power outlet, or power cord. However, if the switch
powers off after running for a while check for loose power connections, power
losses or surges at power outlet. If you still cannot resolve the problem, contact
your local dealer for assistance.
